One of the objects of the invention'is to pro vide sash guidesparticularly designed to facili tate the installation and removal ofwindow sashes. a 7

Another object of the inventionis to provide improved sash guides w ichmore .a wood to metal contact on the siidmgsur'races; in a con structionwhich may readily be assembled Q1 disassembled.

Another object of the inventi n is .to provide metal sash guidesconstructed for ease of fassembly with the window sashes 'aiid with the.

window frames in which they are to be placed to decrease the timerequired for installing windows, and yet provide a window constructionwhich has excellent weather-proofing character.- istics.

Numerous other objectsand -.advantages.of the invention will beparticularly pointed out hereinafter or will become apparent from areading of the specification and upon reference to the drawings.

Referring further to the drawingaat: the v0D- posing sides oftherwinjdow f rameithere. are provided the following assemblies 110i,metal parts. One strip of metal rising :lverticallyqaat the :right sideofthe window :frame is generallyidesignated as-Aand includes. a;fiatslideway le-for theinner sash .flprovided ;at yvertioal' intervals [withholes such as v2 and .aceU'j-shapedschannelmontlon 1173'.

which. fits snugly into a groove 4 provided in the vertical window framemember 5.

Beyond .thechannel 3 toward the outside vof the window is another flatslideway .6 which terminates at a folded flange I, outside of which thestrip is folded back upon itself providing .a channel'betweenthesurfaces 8 and 9 into which the screen guide or retaining strip isfitted, as will be better understood by reference to Figures 1 to3inclusive. The'fiange 1 serves as the out' side guide for the uppersash.

The screen guide or retainer is the structure generally indicated as Biii-Figure 4 and has two portions Ill-and ll which interlock with thepor tions '8 and -9 of the strip A, with the outside retaining flange-I2--folded-back upon itself, as illustrated. The frame of the screen isindicated as l3-i-in Figure 1.

is apparent in Figure :1, the strip C at the left-side of the windowframe is-identic'al with the right hand stripA, as thus far described.Howevenas will be explainedlater, onehas an integral inside -guide -forthe inner sash, while the other has a separable inside guide. Thescreenretainer D is "similar to B.

The -vertical metal stripsA, B, C, andD are assembled and inserted intothe window frame member's-s and -I4, and are secured therein "by na'fls,screws, or in any other suitable manner. Thereafter, theupper sash I5will-be inserted until it occupies the position shown in-Figure 2. Next,the parting strips 11 and 16, which are fielded-strips of metal havingconsiderable resllie'nc'e which tends :to spread their vertical legsapart; are inserted into the channel 3- in the vertical-metal strip -A,-and into the corresponding' chann'el in strip -C. These parting stripshold the sashes snugly against the opposing guide -'-fl'anges, yetpermit them to slide freely from the top to' -thebottom of-the windowframe. The resil-ient legs on the parting strips, bearingonthe--ihsides0f the "channels 3, prevent-any passage-of lairtherethrough, and thus serve also as weather strips.

The-lower' 'sash l 8 --may now be inserted, 'inthe manner indicatedin-Eigure .2,\until it'occupies the f-ullyinserted positionof Figure 1.Thereafter;a-removablestrip, generall indicated as E, having-onelegI9for contactingthe verticalinner surfacebf the lower sash and anotherleg --20 whichmay be inserted between the section 2 of the-guide A andthe:adjacent surface of the windew-frame 5, is-inserted until itoccupies the position shown in sFigureil. After itis in place-the screwsj l, {which had-previously been loosened will now be tightened, thuslocking the section 2 against section 20 which will hold the part Efirmly in place. The screws 2! may be spaced at any desired intervals topass through holes 2 in the guide member A and through V-shaped notches22 provided in the guide E. Thus when the screws are slightly loosened,the member E may easily be withdrawn. By running the inner or lower sashup or down access to all of the screws is easily obtained.

The integral flange 23 on the vertical sash guide shown at the left ofFigure 2 cooperates with the resilient parting strip 16 to snugly guidethe inner sash.

Preferably, the removable guide E and the permanent guide 23 will extendthe full height of the window frame in order to provide a uniform guidefor the inner sash all the Way to the top of the window and to afford auniform appearance. The removable part E, however, is easily removedsimply by the use of a screw driver, while the parting strips l6 and ii,after the inner sash has been removed, are easily pulled out either withthe fingers or with a pair of pliers. Thus it will be :appreciated thatwithout any unusual equipment :in the way of tools, both sashes may beremoved or reinserted with great ease, and yet when they :arereassembled and locked in position the entire :assembly affords anexcellent weather proof con- .struction with metal-to-wood slidingcontacts for lboth sashes.

Referring now to Figure the construction at 'Ithe bottom of the windowframe is exceedingly simple, it being sufficient to provide only asingle strip 0f metal extending across the bottom of the frame, thiselement being generally designated as F and being shaped as indicated toprovide one flange 24% which faces against the bottom window framemember 25, the folded section 26 upon which the screen sash i3 may rest,a middle section 27 located as indicated at the bottom of the sashslideways, and an upwardly extending folded .flange 28 which is adaptedto extend into a groove 229 provided in the lower sash l8. A foldedsection 35 on the part F completes the horizontal :surface on which thebottom of the inner sash :rests. The folded flange 28 and the groove 29in the sash contribute to the weather stripping of the entire assembly.Of course when the inner .sash is being removed it is first lifted offthe flange 28.

Figure 6 shows how the top or the window construction is finished tocooperate with the parts heretofore described to provide a neat, weatherproof construction. A single metal plate extends across the top of thewindow frame, being generally designated by the letter G, and has adownwardly extending flange 3i adjoining a horizontal section 32. Achannel 33 is formed therein similar to the channel 3 and extends into acorresponding groove, not shown, in the adjoining top member of thewindow frame. A horizontal section 35, and a downwardly extending flange3:? complete the metal construction at the top of the window. I providea folded metal insert 36, similar to the folded parting strip ii, to fitsnugly into the channel 33, preventing the upper edge of the .outer sashfrom rattling and holding it snug and in a weather proof relationship.The insert 36 may be made removable or not, as desired. It does notrequire removal during the insertion or removal of the upper sash, forit will be apparent that the upper sash may be lowered before re- ,movalsufiiciently to clear the insert 36.

In view of the narrowness of the parting strips 4 l6 and I! only anarrow ledge 31 need be pro vided on the inner sash to effect a tightseal with the lower margin of the outer and upper sash, as shown inFigure 6.

The construction herein shown and described is easily coordinated with awooden box frame for the window, as is indicated in the drawings:Obviously a metal frame may be used instead of a wooden frame.

Although I have' shown and described one ar:- ticular embodiment of myinvention, I do not desire to be limited to the exact details ofconstruction herein shown and described. It should be understood thatthe invention comprehends all variations and modifications within thescope of the appended claims.
